SHAFT-HANGER.

SPECIFICATION forming pait of Letters Patent No.- 292,879, datedFebruary 5,1884. Application filed February 21, .1883. Renewed January2, 1884. (No model.)

To all whom it may concern/r Be it known that I, JOHN WALKER, of Cleveland, in the county of Guyahogaand State of Ohio, have invented certainnew and useful:

tion, ofthe' box, oil pan, and attachments. Figs. 2 and 8 are detaildrawings of portions 1 of Fig. 1. Fig. 4 is an elevation, one-half inperspective, showing an end view of the frame of a hanger and a sideview of a box, oil-pan,

and portions of a shaft. Fig. 5 is a vertical sectional view of a box,oil-pan, and portions of the hanger, frame, and attachments, andalso oneview ofa scraper or device for scraping the oil from the shaft. Fig. 6,is a plan view of the bottom of an oil-pan, showing also thesaid scraer. Fi s. 7 and 8 are end views I: 7

showing the construction of my device.

A represents the frame of the hanger; B, the box, and G the oil-pannearly surrounding the box. The frame is provided with a verticalcylindrical chamber, a, above and below the box, and in these chambersare placed the hollow plugs a,with their headsin contact with theirrespective set-screws a. The said screws and plugs are for supportingthe box and adjusting it vertically. The box may be provided in thecenter, both above and below, with spherical projections, so placed thatthey shall have a commonradial center, that shall be also the center ofthe box. 7 The projection on the top of the box engages the open end ofthe top plug a, while the projection on the bottom of the box rests in aseat in the oil-pan, which'in turn has a like projection on the bot tom,that engages the open end of the lower plugs a, and thus forms, ineffect, a ball-andsocket bearing for the box and oil-pan. The hangershaving first been placed'in as perfect a line as practicable, it willonly be necessary for the box to turn avery short distance to bringitself always in line with the shaft. It

Will be seen that in this adjustment the open ends of the cups travelover so small a portion of the said spherical projections as to behardly said remaining portions of theprojections, en-

gaging the cups, as aforesaid, would then be in the shape of ringsprojecting from the box,

I prefer making this part of the device. These ring projections aremarked 1), and shown more clearly in Fig. 5. The box is provided withtallow-chambers b, and also with an ori- 'fice, N, in the bottom of thebox, through which, by aid of a wick,'the oil is drawn from the oil-panbelow to lubricate the said box.

The raised'seat in the bottom of the oil-pan, as'shown in the plan view,Fig. 6, is not a continuous ring like the others aforesaid, but is madeof segments of a ring, so placed as to leave spaces 0 between? thesegments for the free passage of oil to this part, as being the lowestportion of the oil-pan, and being also the part from which the oil isdrawn by the wick to supply the box above, as aforesaid.

and it is in this form of projecting rings that The plugs c are forremoving oil or sediment from the pan. The oil-pan extends beyond theends of the box, as shown in Figs. 4 and 5, so as to catch the drip ofoil from said box.

Attached to each end of the oil-pan and directly'under the shaft, arescrapers (shown more clearly in Figs. 4, 5, 6, 7, and'8) for scrapingthe oil from the shaft, so that the oil will fall inside of the oil-pan.This device consists of a weighted handle, D, terminatingin a bent rod,that passes througha hole in the oil-pan, and is attached to the centerof the arm (Z. This arm is provided at the ends with recesses suitablefor attaching scrapers, as shown in the drawings. The attachments of thesaid rod and the said arm are madeby so tight a fit that although theparts can, be turned, yet the weighted end of the rod or handlewillremain in any position in which.

it is placed. It will be seen that the handle a D may be so placed as topress either end of the arm d and its attached scraper against the ofsaid opening.

when in position, support andhold firm these parts of the frame, makingthem equally strong 1 shaft. the arm and its attached scraper shouldbeapplied that will come in contact with the shaft when the shaft has adownward motion. This oil returns byits own gravity to the center of thepan, where it is again used for lubricating the box, the sedimentremaining at the depressions at the bottom of which are the plugs c. Itwill be seen that the top half or cover of the oil-pan has an annularopening in the center, through which the top'plug a passes, so thatthesaid plug rests on the box, and not on the cover of the oil-pan. Thisplug has an oil-hole, a, through which oil may be dis- 3 charged to acavity in the center of the box, terminating in an oil-hole leading tothe shaft below. The set-screws a are for holding and adjustinglaterally the said hollow plugs.

The frame, as shown in Figs. 1 and 2, is made with a cross-sectionalopening inone side large enough for passing a shaft in or out of thehanger. This opening is provided witha block, A, that is secured by abolt passing through the said block, and also through suitable lugsattached to the frame on each side The said block and bolt,

with the other parts. By removingthis block and bolt, the shaft may betaken out of the hanger without removing the pulleys, collars,couplings, or anything, in fact, from the shaft. The block A may beprovided with an arm suitable for supporting any desired belt-shiftingdevice. This arm may be made hollow, as shown at G, Fig. 2, inclosing anextensionarm, g, secured by the set-screw g, by means of which thebelt-shifting device may be adjusted to the size of the pulley .used.

Figs. 9, 10, 11, 12, and 13 illustrate the process by which the framesfor these hangers are made.

Fig. 9 represents a pattern for the hangerframe,with the eore-prints Mattached, ready for making a mold for casting the said frames. Theblocks A are first made with a lip, a, above and below, as shown inFigs. 12 and 13, and with a hole, as shown by the dotted lines. A coreis inserted in the hole and projecting on each side, as. shown in Fig.11, and in this condition it is laid in the mold with the line x x ofFig. 11 coincident with the line w w of Fig. 9'. After placing cores inthe prints M, the mold is completed and the castings made.

.After the casting is sufficiently cool, the block A is driven out,leaving that side of the frame as shown in Fig. 10. The lips n will haveformed recesses in the lugs of the frame, that will serve as guides tothe block A when it is desired to place it again in the frame.

It will be seen that 'the core placed in the block A, as aforesaid, andextending through the lugs 011 either side will make a straight holefora bolt without reaming or expending other labor upon it.

' Blocks with arms, as at G, maybe snbsti- To secure the best result,that end of having one of its sides divided, of the block secured in theopening thus formed by abolt, and provided with an extension-arm forsupporting the belt-shifting or other device, and capable of beingadjusted lengthwise, substantially as shown and described.

2. The combination, with a shaft-hanger having one of its sides divided,of theblock secured in the opening thus formed by a bolt, and providedwith a hollow outer arm, and the inner arm fitting therein and adaptedto be longitudinally adjusted, substantially as and for the purposedescribed.

3. In a shaft-hanger, the oil-pan having a boss resting on aVertically-adjustable tubular seat below, the oil-box having a ring-likeproj ection on its under side, adapted to rest upon the inner side ofsaid boss, the upper side of the box being provided with a support, andthe pan adapted to fit around said support, whereby the box and the panmay adjust themselves to the line of the shaft, substantially asdescribed.

4E. The combination, in a shaft-hanger, of the oilpan, constructed,substantially as described, with the journal-box located within thesame,having a ring-like projection adapted to be supported by the pan,and the pan constructed in a cylindrical form, whereby the box isinclosed, substantially as described.

5. The combination, in a shaft-hanger, of a cylindricallike oil pan, andan inclosed journalbox having a ring like projection adapted to besupported by the pan, with a scraper constructed to normally bearagainst the shaft and scrape the oil therefrom, substantially asdescribed.

6. The combination, with the weighted handle D, terminating in a bentrod, of the-arm d, .so arranged that either end of the said arm or itsattached scraper may be applied to the shaft, substantially asdescribed, and for the purpose set forth.

In testimony whereof I sign this specification,i.n the presence of twowitnesses,this 13th day of February, 1883.
